HEAT TRANSFER LAB
Overview
In Heat Transfer laboratory, the students will enrich their knowledge practically on heat transfer process which they studied in theory subject. In this lab students will practically come to know steady and unsteady state transfer of heat in fluid. In this lab students will conduct the experiments to find thermal conductivity of different materials, overall heat transfer coefficient of composite wall, Heat transfer coefficient of pin-fin. Also students will come to know difference between conduction, convection and radiation through experiments. Students also studies the performance of heat exchanger devices. Lab is provided with proper ventilation, space and sufficient lighting.
Laboratory Area: 210 Sq. Mts
